Retrieving a bit column from sql database in VB NET

Question

I have encountered a problem where in my database I have a column that is a bit either 0 or 1 specifying if a user is an admin or is account suspended or not. And in my VB code

Answer 1

Try rdr.GetBoolean(3) to get Bit values. A bit in SQL Server is the same as a boolean in VB, except it uses 1 and 0 instead of true and false.

Answer 2

You can specify the name of the Data Item rather than the index. Such as:

newrow.Item("SESSuspended") = rdr("SESSuspended")

Answer 3

You want

  newrow.Item("SESSuspended") = rdr.GetBoolean(2)
  newrow.Item("SESAdmin") = rdr.GetBoolean(3)

You should also change these lines

  dtRequests.Columns.Add("SESSuspended", System.Type.GetType("System.Byte"))
  dtRequests.Columns.Add("SESAdmin", System.Type.GetType("System.Byte"))

to

dtRequests.Columns.Add("SESSuspended", System.Type.GetType("System.Boolean"))
dtRequests.Columns.Add("SESAdmin", System.Type.GetType("System.Boolean"))

Answer 4

Use GetBoolean

Although there is no "boolean" SQL data type, bit maps to .net boolean
